/* Parse a Modula-2 expression from text in a string,
|
|
|
|
|
and return the result as a struct expression pointer.
|
|
|
|
|
That structure contains arithmetic operations in reverse polish,
|
|
|
|
|
with constants represented by operations that are followed by special data.
|
|
|
|
|
See expression.h for the details of the format.
|
|
|
|
|
What is important here is that it can be built up sequentially
|
|
|
|
|
during the process of parsing; the lower levels of the tree always
|
|
|
|
|
come first in the result.
|
|
|
|
|
|
|
|
|
|
Note that malloc's and realloc's in this file are transformed to
|
|
|
|
|
xmalloc and xrealloc respectively by the same sed command in the
|
|
|
|
|
makefile that remaps any other malloc/realloc inserted by the parser
|
|
|
|
|
generator. Doing this with #defines and trying to control the interaction
|
|
|
|
|
with include files (<malloc.h> and <stdlib.h> for example) just became
|
|
|
|
|
too messy, particularly when such includes can be inserted at random
|
|
|
|
|
times by the parser generator. */
